I learned that instructional systems design is about aligning course goals, content, activities, media, and assessments so the online learning experience is clear, engaging, and effective. I also learned how to use graphics, animations, and other media strategically, while making sure the course is built around sound design principles and well-defined course specifications. I intend to apply this knowledge by planning my online courses more carefully, checking that each activity supports the learning objectives, and choosing media and design elements that improve understanding rather than distract from it.
